Definitions

  • This invention relates to an exercise and rehabilitation apparatus and particularly to a resistance apparatus that can be used with or without a treadmill that includes a means for exercising a user's leg and/or arm and its connecting muscles with an independently adjustable restraining or resisting force for each individual leg and/or arm.
  • Exercise equipment includes a multitude of devices for use with arm and leg members for the purpose of stimulating and developing muscle tone, strength and agility as well as for reducing weight and fat tissue. It is recognized that walking is a natural form of exercise and that the use of a treadmill apparatus has definite beneficial values in walking, jogging and running exercises by providing a movable surface on a stationary platform unit. The speed and slope of the walking surface can be controlled to the needs and fitness level of the participant. While the treadmill has many advantages, fitness enthusiasts, physical therapists, trainers and others may desire to provide additional beneficial muscle exercises concurrently with the type of exercise provided by a treadmill.
  • the present invention provides a system for adding and controlling exercise resistance force to the leg, thigh, and calf muscles as well as certain other body muscle groups such as the arms. This imposition of force is applied to each leg or arm in an independent manner. More specifically, the major leg muscles involved are the quadriceps, the upper thigh, anterior and posterior, hamstrings, buttocks and lower back. The major arm muscles involved are the deltoids, triceps, biceps, brachialis, flexors and the other interacting arm muscle groups. Additionally, muscle groups in the body which interact with the leg and arm muscles and other major muscle groups of the body can be exercised.
  • the subject invention is directed to a resistance apparatus for use in exercising and rehabilitation of a user's limbs.
  • the resistance apparatus includes a generally drum shaped housing having interior and exterior portions.
  • the housing includes a shaft opening that is sized and shaped to accommodate a shaft and a cable opening for threading a cable from the interior portion of the housing to the exterior portion of the housing.
  • the apparatus also includes a shaft supported by the housing at the shaft opening, and a cylindrical reel sized and shaped to fit within the interior portion of the housing.
  • the reel has an interior portion, an outer surface and at least one reel opening, with the reel outer surface being configured to support a cable that is wound around the outer surface of the reel.
  • the reel contains a spiral spring having first and second end portions, with the first end portion being connectable to the shaft and the second end portion extending through the reel opening.
  • the spiral spring is configured to wind around the shaft and to provide controlled torsion/tension to the spiral spring.
  • the apparatus includes an elongated cable having first and second end portions, with the first end portion being attached to the second end portion of the spiral spring.
  • the second end portion of the cable extends through the cable opening in the housing and includes a connector and cuff for releasable attachment to selected individual limbs of an user.
  • the spiral spring pays out cable from the housing in order to provide independent adjustable resistance to the individual limbs of a user during exercise or rehabilitation.

  • Each spool 22, 24 is connected to one end of an adjustable spiral, or clock spring 30 or 32 located in the journal 36.

  • the location of the arm 34 adjusts the relaxed location of an ankle cuff 40 (the length of the line 26) relative to the ends 42 of the frame member 16, 18.
  • a normal foot location on the treadmill belt 13 is a location of a foot arch in alignment with the ends 42.
  • the spring 30 When a step is taken, the spring 30 is tensioned and requires muscle exertion to move to the forward step position as shown in Fig. 1. At the end of a step, the individual again must exert muscles to counteract the return torsion/tension force of the spring 30.
  • the tensioning of the springs 30, 32 is a fairly uniform function of the spring forces and that each leg or arm is independently controlled. Additional control of the torsion/tension force of the springs 30, 32 in either a forward or rearward step motion, is effected by independently adjustable brakes 55 applied to the spools 22, 24. By adjusting the braking force on the spools 22, 24, the range of torsion/tension control of the springs is increased. As shown in the drawings, the line or wire 26 or 28 passes from the spools 22 or 24 to a first transverse pulley and gimbal 44 located on a vertical post 46.
  • the line passes through a slot 48 in an elongated and transverse tension arm 50 to a second pulley and gimbal 47 at the end of the arm 50 and thence to an ankle cuff 40.

  • additional torsion/tension can be required by a leg motion in the initial step and when the foot is lifted.
  • the tension arm 50 has a limited arc movement by virtue of limit stops between the post 46 and the arm 50, the torsion/tension is selective to the initial motion until a limit stop is reached where the torsion/tension is applied to the spring 30.

  • the resistance force can be controlled. Changing any of the dimensional characteristics of the spring 150 will alter this force, however, it is easiest to alter the width and/or length of the spring 150 while maintaining a constant thickness.
  • the width of the spring 150 By selectively changing the width of the spring 150 at certain distances between its first and second ends 152, 154, it is possible to obtain either a constant or variable resistance force as desired. This ability allows the tension of the resistance apparatus 100 to be applied in a preselected manner determined by the user.
  • a further advantage of using the spiral spring 150 in the resistance apparatus 100 is that the immediate recoil of a spiral spring, it works with the speed of the body so that both the body and the spring are working in unison. Because both the body and the spring are in unison, there is constant resistance on the muscles of the body, producing the most effective kind of exercise. Since the preferred method of exercising is to maintain constant resistance on the body at all times, the resistance apparatus 100 of the present invention provides this constant tension.

Abstract

La présente invention concerne un appareil d'exercice destiné à l'exercice et la rééducation des membres d'un utilisateur. Cet appareil comporte un carter de la forme générale d'un tambour dans lequel est ménagée une sortie d'arbre d'une forme et de dimensions convenant au passage d'un arbre. Le carter comporte également une sortie de câble permettant de laisser filer un câble de l'intérieur du carter vers l'extérieur du carter. L'appareil comporte aussi un arbre reçu dans le carter au niveau du passage d'arbre, et une bobine cylindrique qui tient à l'intérieur du carter. La bobine renferme un ressort spirale dont une première extrémité est reliée à l'arbre, la seconde extrémité sortant par un orifice de la bobine. Le ressort spirale est conformé de façon à s'enrouler autour de l'arbre et de façon à assurer une torsion/tension contrôlée du ressort spirale. L'appareil est pourvu d'un câble dont une première extrémité est frappée sur la seconde extrémité du ressort spirale, la seconde extrémité du câble ressortant par la sortie de câble. Le câble est équipé d'une jonction et d'un bracelet permettant d'attacher le câble à des membres choisis de l'utilisateur et de l'en détacher. Pendant l'utilisation, le ressort spirale permet de débiter du câble hors du carter de façon à créer des résistances réglables indépendamment s'appliquant aux différents membres et autres groupes de muscles d'un utilisateur pendant l'exercice ou la rééducation.
